net/bluetooth/mgmt.c: In function ‘read_local_oob_ext_data_complete’:
net/bluetooth/mgmt.c:6474: warning: ‘r256’ may be used uninitialized in this 
function
net/bluetooth/mgmt.c:6474: warning: ‘h256’ may be used uninitialized in this 
function
net/bluetooth/mgmt.c:6474: warning: ‘r192’ may be used uninitialized in this 
function
net/bluetooth/mgmt.c:6474: warning: ‘h192’ may be used uninitialized in this 
function

While these are false positives, the code can be shortened by
pre-initializing the hash table pointers and eir_len. This has the side
effect of killing the compiler warnings.
